I've had my betta for about a month now and I've got to say I've never seen him poop or found any cleaning his tank. I'm really confused and worried about him. I've been feeding him Hikari Betta Bio-Gold pellets about 3 in the morning and 2 at night. He doesn't look bloated. Yesterday he kept spitting out the pellets so I got some flakes and blood worms. He spit out the flakes but loved the worms.
He has been fine so far but just started acting lazy the past few days stopping swimming and resting on plants, sitting at the bottom, and what not.
What should I do to help him? What would his poop even look like?
